In the United States and Canada,bats use one of two strategies to survive winter: They either migrate south,or they hibernate.Recently,those that hibernate seem to have come under attack by a fungus,Geomyces destructans (Gd),an attack that is occurring from Missouri to southern Canada.Many infected bats have a delicate,white filamentous mat on their muzzles,which is referred to as white-nose syndrome (WNS).The fungus invades the bat tissues,causes discomfort,and awakens the bat from its hibernation.The bat fidgets and wastes calories,using up its stored fat.The bat then behaves abnormally,leaving its cave during daytime in winter to search for food.Their food,primarily insects,is scarce during the winter,and the bats ultimately starve to death.Since 2007,it is estimated that up to 1 million bats have perished from WNS. -Gd is a cold-loving fungus.Thus,which characteristics of abnormal bat behaviour can be most expected to favour the growth of this fungus?
A)shifting roosting location to the mouth of the cave during winter B)searching for food during winter C)searching for food during the day D)All three of the options listed are correct. E)Only two of the options listed are correct.
